1. Introduction

1.1 Long-term Goal

As a part of the South Florida Ocean Measurement Center (SFOMC), NSU and USF deployed a

three-dimensional mooring array coordinated with the OSCR with acoustic Doppler current

profilers (ADCP) and a combination of inductively coupled and/or self-recording

temperature/salinity sensors. In 2004, a data report was written including data from 1999 to 2000

(Soloviev et al. 2004).

The long-term goal of the project is to provide necessary monitoring of the physical-

oceanographic environment for the SFOMC Range and to provide access to information on local

currents on the Southeast Florida shelf. This report is a presentation of the existing fourteen year

data set on the Dania Beach, Florida shelf obtained with an ADCP mooring deployed at an 11 m

isobaths, a subsurface buoy deployed at a 240 m isobath on the Miami Terrace, and an AWAC

temporarily deployed at an 11 m isobath in Summer 2010.

Continuation of long term observations at the existing mooring locations is expected to help the

Broward County, FL and state of Florida resource trustees to monitor the state of the coastal

ecosystem. The data will also be useful for numeric models and for research projects. In addition,

the array provides data useful for understanding a variety of scientific questions. These questions

include: What are the dominant modes of interaction between the nearby Gulf Stream and the

shelf/near shore circulation? Are these events driven by the wind, Gulf Stream Meanders,

propagating continental shelf waves, or near-shore eddies? What is the structure and temporal

variability of the internal-wave field?

1.2 Objective

The objective of this project is to provide ADCP data from the Nova Southeastern University

Oceanographic Center (NSUOC) ADCP bottom-mount mooring (off Dania Beach) at 11 m

isobath, from the subsurface Calypso ADCP mooring (off Pompano) at 244 m isobath, and from

the AWAC bottom mounted system at 11 m isobath.

1.3 Potential Users of Data

Some potential users of this data include Port Everglades related users (small boaters, port pilots,

container ships, petroleum tankers), US Coast Guard search and rescue, US NAVY SFTF,

hurricane forecasters, commercial and recreational fishers, county pollution regulators, beach

erosion specialists, coastal managers, turtle program scientists and managers, FDEP water

quality specialists, coastal resource managers, USGS, and water treatment facility managers.

1.4 Data

This Data Report presents an approximately fourteen year dataset collected from a bottom

mounted ADCP (NW (W) Bottom Mount) at an 11 m isobath deployed on the Dania Beach shelf

and a four year dataset collected from a subsurface ADCP (Calypso subsurface buoy) at a 240 m

isobath on the Miami Terrace near Pompano Beach. For a two month period in summer 2010, an

AWAC system (AWAC Bottom Mount) was also used to collect data off the Dania Beach shelf

at an 11 m isobath. For more details of the experimental design of each unit, see sections 2.1,

2.2, and 2.3. The data from the moorings are provided to users via DVD.

2. Experimental Design

The location of the array is shown in Figures 1 and 2. The NW (W) Bottom Mount and AWAC

Bottom Mount are located 11 meters deep on sand stretch between two reef tracks. The Calypso

subsurface buoy is located 240 meters deep in open waters; this location was chosen to satisfy

requirements by the Calypso Project. Photographs of the NW (W) Bottom Mount, AWAC

Bottom Mount and Calypso subsurface buoy are shown in Figure 3. Details of the designs are

given below (Table 1):

Figure 1. Map of the NW (W) Bottom Mount, AWAC Bottom Mount, and Calypso Subsurface

Buoy locations. Coordinates of each mooring are presented in Table 1. The ADCP Bottom

Mount is an upward looking WHS600 or WHS300 Acoustic Doppler Current Profiler at an 11 m

isobath. The Calypso Buoy is a subsurface buoy 10 m above the sea floor at a 240 m isobaths

with an upward facing WHLR ADCP and a downward facing WHS300 ADCP. The Nortek

AWAC is an upward looking ADCP located at an 11 m isobath, 30 m north of the ADCP Bottom

Mount.

2.1 NW (W) Bottom Mount

The NSUOC bottom ADCP mooring was deployed in June 1999 on the Southeast Florida Shelf

(Dania Beach, FL) as a part of a working relationship between NSU and USF in the framework

of South Florida Ocean measurement Center (SFOMC). In 1998, the Office of Naval Research

provided initial 5-year funding to NSUOC for this project. The mooring was maintained by the

NSUOC using a combination of internal NSUOC funding and other ongoing projects. At this

point, almost a 14 year data set has been collected at this mooring location.

The NW (W) bottom mount consists of a concrete anchor, and an upward looking RDI

Workhorse Sentinel ADCP mounted on a trawl resistant bottom rack. The concrete anchor was

manufactured at the USF marine shop. The NW (W) bottom mount was deployed from the R/V

Stephen (FAU) on 25 June 1999 at an 11-m isobath (26° 04.226 N 080° 05.660 W) and was

installed in an internal recording mode. The ADCP bottom mount has been maintained

continuously since its deployment in 1999; the data from all sensors are periodically

downloaded. The concrete rack was re-aligned and redeployed on November 19, 2005 (26°

04.1344 N 080° 04.134 W) after being moved by Hurricane Wilma and was again re-aligned in

2010.

2.2 Calypso Subsurface Buoy

The Calypso subsurface buoy consists of an acoustic modem, a Workhorse LR 75-1-2 ADCP, a

Flotation Technologies flotation buoy, a submersible strobe light, an ARGOS satellite

transmitter, a Workhorse Sentinel 300 ADCP, and a 2000 pound anchor system. A diagram of

the buoy design can be seen in Figure 4.

It was constructed for Calypso LNG LLC Project and deployed from the R/V Stephan on

January 23, 2007 at 26° 11.280 N 079° 58.278 W. The Calypso subsurface buoy sits 10 m above

the ocean floor at approximately 240 m depth. It was installed in an internal recording mode with

near real-time access by an acoustic channel. The buoy has been serviced several times since its

deployment in 2007 through 2010. The data from all sensors were periodically downloaded.

The project was funded by Calypso LNG LLC (SUEZ North America Inc.).

2.3 AWAC Bottom Mount

The AWAC bottom mount consists of a battery pack, an Acoustic Wave And Current Profiler, a

circular polystyrene platform for the battery pack and AWAC, and a rebar anchoring system. The

AWAC system is a NortekUSA product, and the configuration was assembled in-house. It was

deployed from the R/V Panacea in June 2010 at 26° 04.243 N 080° 05.660 W. The AWAC

bottom mount was installed in an internal recording mode. It was deployed temporarily during

June and July 2010 (Figure 2b).

3. Data Sets

3.1 NW (W) Bottom Mount

This section describes the contents of the ADCP Bottom Mount directory structure and contains

the data from the NW (W) Bottom Mount. See Figures 1, 2 and Table 1 for more details about

the array configuration on the Southeast Florida Shelf.

The DVD sub-directory labeled \data\W-buoy contains folders with data from the bottom-

mounted Workhorse ADCP in two different formats: Binary (Raw) and Matlab (.mat). Each

folder is labeled by the date at the beginning and end of the record. For example: the record

se666000.000 is in the folder ‘25Jun99_10Aug99’ because the beginning of the record is June

25, 1999 and the end of the record is August 10, 1999.

The data in the Matlab format have been preliminary processed, which was accomplished by

reviewing the data in WinADCP (supplied by RDI). The beginning and end of each data file was

trimmed to exclude any data during a time that the instrument was disturbed by boat and/or

divers’ operations (Table 2).

The Matlab files contain the converted data processed from the raw data by the WinADCP

software. The user is cautioned that a few of the Matlab files contain a small error in the time

interval that is introduced in the conversion to Matlab format. These errors have been corrected

manually. The correct ensemble intervals can be found in Table 2.

The Matlab files are named according to the date (bin/ensemble) of deployment when the

instrument was determined to be taking appropriate measurements. The Binary (raw) data does

not, however, follow this convention. The data files' name and extension differ between the Raw

and Matlab files; associated files are listed in Table 2. The Matlab variables are described in

Table 3 below.
